Sky+ is a hard drive recorder and uses disc space to record the programme
you are pausing. When you rewind/catch-up you are playing the recording. All
time-slip systems, whether using DVD or HDD, rely on their ability to play
sections of a recorded file that is still being recorded, i.e. is
incomplete. How far back depends. I don't own a Sky+ but believe it will
buffer an entire program, if you pause, up to about an hour, something like
that. So it isn't a buffer as such, it is the recording medium you would
use for any recordings.

Pressing time-slip to pause a recording begins a recording. You can't
rewind before that point, obviously. If you are already recording a
programe, you can rewind at will. This sounds so obvious I wonder if I have
mis-understood your question - sorry!! I think that what happens to the
recording snippets left over at the end is system dependent.
